Project description

The City of Ottawa is renewing aging infrastructure and revitalizing the right of way in the northern section of Old Ottawa East. The project area is predominantly bounded by the Rideau Canal to the west, King Edward Avenue to the north, Highway 417 to the east and Hawthorne Avenue to the south. A 160-metre section along Colonel By Drive/Echo Drive, which extends south of Hawthorne Avenue to Immaculata High School, is also included in the project limits. This work is being conducted to replace aging combined sewers with separate storm and sanitary sewers, replace sections of older watermains, and reconstruct the roadways.

The Greenfield Avenue, Main Street, Hawthorne Avenue et al. reconstruction project is a multi-year project, with advanced construction work commencing in late summer 2021. In 2022 remaining work was completed on the advance contract. The main contract was tendered in late-summer 2022 with award to GIP Construction Ontario East Ltd (GCOE), formerly Aecon, in fall of 2022. The project's major components are expected to be complete in 2025. Specific project phasing and construction schedules will be communicated to the public throughout the project.

Project limits

The following street segments have been identified for reconstruction:

Colonel By Drive (Graham Avenue to Main Street)
Concord Street north (Echo Drive to Havelock Street)
Echo Drive (Immaculata High School to Graham Avenue)
Echo Drive (dead-end at Highway 417 to Concord Street north)
Greenfield Avenue (Main Street to King Edward Avenue)
Harvey Street (Echo Drive to Main Street)
Hawthorne Avenue (Colonel By Drive to Main Street)

Construction 2025

This notice is to advise that construction in your neighbourhood will resume in March 2025. This work is being conducted to rehabilitate sewers, watermains and roadways in your community.

The City is committed to maintaining regular communication with residents directly affected by an infrastructure project.

What: The Greenfield-Main-Hawthorne et al. reconstruction project involves the construction of sewers, watermains, electrical infrastructure, roadways, sidewalks, cycle paths, intersection modifications, and streetscape/landscape treatments within the City’s right of ways.

Why: The purpose of the overall Greenfield, Main, Hawthorne et al. reconstruction project is to replace aging combined sewers with separate storm and sanitary sewers, replace sections of older watermains, and reconstruct the roadways, including the implementation of improved street features for the betterment of all road users in your community.

When: Construction will continue/resume in March 2025. The initial activities will include mobilization to site including site trailer setup, miscellaneous gas relocations, electrical/utility works and deep underground sewer work at the Main Street and Harvey Street intersection. The project is being delivered in three phases, with expected completion for the fall of 2025.

The 2025 phase of work is planned to occur between early March and extend late summer/early fall as follows:

Sewer, watermain and surface renewal:

Echo between dead-end at HWY 417 & Main
Harvey - between Main & Echo
Main – between Harvey & Greenfield
Sewer abandonment under the Rideau Canal
Concord - between Montcalm & Havelock

Sidewalks, cycle tracks, wear course paving and miscellaneous landscaping:

Hawthorne – Colonel By to Main
Main – Greenfield & Echo
Echo – Main to Concord
Concord – Echo to Havelock
Greenfield – Main to Hwy 417 on-ramp including Old Greenfield
Montcalm – Greenfield to dead end, north of Concord

Where: Please refer to the key plan for street segments affected by construction in 2025. Construction may occur concurrently in separate areas.

Who: Green Infrastructure Partners (GIP), formerly Aecon, has been awarded the construction contract for the Greenfield-Main-Hawthorne et al. reconstruction project.

Traffic impacts

Lane reductions and closures of some street segments to local traffic only can be expected during construction to accommodate the work. Access to local businesses and private properties will be maintained throughout the construction period. Should lane or road closures be required as part of the project in your community, advanced notice will be communicated to impacted residents and businesses. Signs will be posted and flagging will occur where required.

Garbage collection

The contractor is aware of the garbage collection schedule and is required to maintain access so that garbage can be collected at the curb. If vehicular access is interrupted for any reason, the contractor is responsible for moving the garbage from the homeowner’s curb to a common location where it can be picked up. Empty containers will then be returned to the appropriate homeowners/businesses.

On-street parking and driveway impacts

To allow the work to be completed in a timely manner, on street parking may be prohibited during the construction period. Signs will be placed 24 hours in advance indicating the parking prohibition. The contractor is obligated to provide 24-hour notification of temporary loss of access/egress. In the event that access to your driveway is restricted due to construction activities, a Temporary On-Street Parking Permit (orange form) will be distributed to permit on-street parking within two blocks of your residence.

Residents with electric vehicles will need to find alternative charging arrangements when access is restricted. The use of extension cords by residents within the public right of way, particularly for charging EV vehicles, is not permitted. Due to the dynamic nature of the construction there may be occasions when construction equipment and/or contractor vehicles may impose short term impacts to access/egress to your property. The operators of these equipment/vehicles will be present and can accommodate access/egress upon request. Please just be patient in this regard. Should you have additional concerns about reduced access, such as business deliveries or accessibility requirements, please contact the project manager.

Pedestrian and cyclist access

During the course of an infrastructure project, there will be occasions when a road may require closure to complete construction activities. The City will make every effort to ensure pedestrian and cyclist access can be maintained but there may be occasions, such as a bridge renewal, where access may be temporarily removed for all users until it can be safely restored. During those occasions, an alternate route will be identified with directional signs.

Impacts on transit

On occasion, transit service may be impacted. Where possible, a bus stop will be relocated to a temporary location until the construction activity is completed. All changes to transit service will be communicated on OCTranspo.com(link is external).

Working hours

The City of Ottawa Noise By-law (2017-255) allows construction activity to occur weekdays between 7 am and 10 pm. On Saturdays, work is permitted between 7 am to 10 pm, while Sundays, statutory and public holidays work is permitted between 9 am to 10 pm. Should night work or weekend work be required as part of the construction project, you will be notified in advance by the City. An exemption to the Noise By-law will be required for night work and communicated in the same notice.

Temporary water services

During the time period when the old watermain is being replaced on your street, water will be supplied to buildings by temporary water lines. While your property is on this temporary service, your usage will be estimated since the temporary service is not metered. Your water bill will be based on your past average usage. If you have any questions, please contact Revenue at 613-580-2444 or WS-Billing@ottawa.ca(link opens email application).

Municipal fire suppression will continue during the construction period. Please note that private fire suppression systems may be impacted due to temporary water lines. If you have a private fire suppression system, you should make arrangements with a qualified fire protection services company to assess the extent of the impact. For information on minimizing fire risk, contact the City Fire Services at 613-580-2424, ext. 15371 or fireprevention@ottawa.ca(link opens email application).

Impact on the right of way and adjacent private properties

City construction is conducted within the City’s right of way but may result in some disruption to part of the private property directly adjacent to the work. The City, through the contractor, will reinstate any sections of landscaping, driveways and walkways that are disturbed by construction. However, if you have plants or any other assets located within the City’s right of way that you want to preserve, you may want to move them in preparation for the construction work.

Lawn irrigation systems and heated driveways

If you own a subsurface lawn irrigation system or heated driveway system, please notify the City’s Project Manager.

Property damage

As part of the contract, the contractor is assuming full responsibility for the construction work until it is entirely complete as well as any damage to private property resulting from these construction activities. In the event of such occurrences, all claims for damages should be immediately reported both verbally and in writing to the contractor and to the City’s on-site representative. This will ensure prompt notification of appropriate authorities to complete the claim investigations.

Construction disruptions

GIP will take every precaution to minimize interruptions to the normal life of your family and/or operation of your business, but as you can appreciate, there may be some inconvenience during the course of the operation of the work, such as delays and traffic detours when travelling through the construction zone, noise, dust and vibration. These inconveniences are sometimes unavoidable in order to complete the required work of infrastructure renewal. Should the conditions seem excessive, please contact the City’s Project Manager.

Pre-construction survey (January 2025)

Beginning late March 2025, the City of Ottawa will continue construction along various streets as part of the Greenfield-Main-Hawthorne et al. Reconstruction Project. In advance of 2025 construction, a survey of your property is encouraged.

Who: The contractor, GIP Construction Ontario East Inc., has been retained to undertake the construction work. Englobe Corp. has been hired by GIP to conduct pre-construction inspections of the homes and properties within a 30-meter radius of the construction area.

What: GIP is assuming full responsibility for the construction work until the construction project is entirely completed. GIP is also required by the City to carry liability insurance before any work may proceed. You will be asked by representatives of Englobe Corp. for permission to survey your property before adjacent construction commences. It is to your benefit to allow the inspection to be conducted on your property, as it may assist with establishing the impact, if any, that construction has had at your property after work is complete. In addition, you may wish to complete your own survey of pre-construction conditions on your property. Your survey should include photographs.

Why: Pre-construction surveys are completed to document existing conditions before construction commences.

When: Pre-construction survey requests have commenced for areas where construction is scheduled for 2025. Pre-construction surveys will be phased to be conducted in advance of proposed construction.

A map showing the completed construction and upcoming work areas as listed within this article.

Notable changes to the previously proposed 2024 work plan:

Concord Street North – Montcalm Street to Havelock Street: This work was postponed in its entirety to 2025 as the watermain in this section was found to be much older than existing City records indicated. Addition of this section of watermain to the contract along with new water services to the property line will be done along with the planned sanitary and storm sewer work.
Hawthorne Avenue – Colonel By Drive to Main Street: Sections of curb and sidewalk in front of the new development on the south side of Hawthorne Avenue, and in front of Ballantyne Park on the north side of Hawthorne Avenue have been deferred until next year to avoid damage due to construction activity. Final concrete sidewalks on the approach to Pretoria Bridge will be deferred to 2025 pending relocation of traffic poles. Top lift paving has also been deferred for the same reason.
Main Street – Harvey Street to Greenfield Avenue: Electrical and communications utility work in support of the undergrounding of the overhead lines has been largely deferred until spring 2025, as has the associated curb, sidewalk and cycle tracks located above the ducts. Temporary reinstatement of sidewalks with asphalt in these areas can be expected for over winter. Construction of the high-level storm sewer, from Harvey Street to Main Street has also been deferred.
Greenfield Avenue – Concord Street North to Main Street: Electrical and communications utility work in support of the undergrounding of the overhead lines is well underway. The associated curb, sidewalk and cycle tracks located above the ducts have been partially deferred to 2025. Some temporary reinstatement of sidewalks with asphalt in these areas can be expected for over winter, while other areas closer to Concord Street North may have concrete curb and sidewalk.
